1 Product Orientation

1.1 Overview

This document describes HUAWEI UGW9811 V900R011.

The Huawei-proprietary UGW9811 (UGW9811) is a unified packet gateway that can be

deployed in 2.5G General Packet Radio Service (GPRS) systems, 3G Universal Mobile

Telecommunications Systems (UMTSs), or Evolved Packet Core (EPC) systems.

1.2 3GPP System Evolution

The mobile network has developed from the 2G global system for mobile communications

(GSM), the 2.5G general packet radio service (GPRS), and the 3G universal mobile

telecommunications system (UMTS) to the enhanced 3G (E3G) long term evolution (LTE).

Mobile networks cover wide areas, achieve high-speed wireless data transmission, and allow

access to the Internet.

Brief Description of the Existing Network

With the evolution of the radio technologies, existing networks have evolved from the

2G global system for mobile communications (GSM) to the 2.5G general packet radio

service (GPRS) and lastly the 3G universal mobile telecommunications system (UMTS).

This evolution has allowed mobile communications to achieve wide area coverage,

high-speed radio data transmission, and integration with the Internet. The result is that

the consumer can enjoy diversified services like voice, data, and video applications and

"any time, any place" communication delivered in a personalized fashion.

Currently, with the robust development of services and diversification of requirements,

the 3G UMTS architecture is hindered by inherent limitations:

− Insufficient support for packet switched domain (PS) network services. Generally, the

3G UMTS system is capable of supporting only non-real time services and depends

on the circuit switched domain (CS) to bear voice services. This results in separate

network operations for PS and CS, which hinders centralized network maintenance

and management and increases OM expenditures.

− Low efficiency in routing and forwarding data due to network overlayer. Therefore,

network performance needs to be improved.





2

− Incapable of supporting multiple radio access systems. The development of service

terminals in processing capabilities and radio access capabilities provides an impetus

for the integration of multiple radio access technologies.

Brief Description of the EPC Network

To maintain a competitive edge in future networks, the 3rd Generation Partnership

Project (3GPP) began to research the implications and long-term evolution of 3G

technology—E3G technology. E3G refers to the enhanced 3G system, which has the

following features:

− The technology for the air interface in E3G is LTE.

− The core network evolution program of the LTE project is SAE, also known as the

Evolved Packet Core (EPC).

The 3GPP EPC project is working on a long-term program to explore key technologies

in the next 10 years. According to the 3GPP evolution design, the EPC system provides

the following features:

− Overall packetization of the network architecture: The all-IP network contains only

the PS. Voice services are jointly provided by the PS and the IP multimedia

subsystem (IMS), enhancing the network efficiency and performance.

− Delayered network architecture: The network architecture becomes simpler so that

networks can be deployed more easily and data transmission delay is greatly reduced.

The S-GW and P-GW may be implemented in one physical node, delayering the

network.

− Support for multiple access technologies: The EPC system supports interworking

with the existing 3GPP system. In addition, it supports access of users in non-3GPP

networks and provides roaming and handover between the 3GPP and non-3GPP

networks for users.

− High data transmission rate: The peak rate of the downlink traffic reaches 100 Mbit/s

and the peak rate of the uplink traffic reaches 50 Mbit/s.

− Fast deployment: Thanks to the simplified architecture, networks can be deployed

rapidly to adapt to the requirements of the changing services.

− Enhanced real-time services: The EPC system supports real-time services and reduces

the setup time for service connections.

Figure 1-1 shows the evolution of the network architecture in the 3GPP standard.

eNodeB: evolved NodeB

Serving gateway: provided for implementing the

service forwarding between the gateways

MME: mobility management entity

PDN gateway: packet data network gateway

The EPC network is designed for high-speed mobile packet data services. The network

architecture is greatly simplified. Compared with the earlier versions, the architecture is

optimized in the following ways:

The LTE base stations are directly connected to the EPS core network. The previously

independent base station controller (BSC) functions are integrated into the eNodeB.

The PS domain is restructured as follows:

− The signaling plane and forwarding plane of the serving GPRS support node (SGSN)

are separated from each other. The signaling function of the SGSN is implemented by

the mobility management entity (MME), and the forwarding function of the SGSN is

implemented by the S-GW.

− The functions of the GGSN are provided by the P-GW.

− The S-GW and P-GW may be implemented in one physical node, delayering the

network.

The network converges with the non-3GPP networks such as CDMA2000 high rate

packet data (HRPD) network, providing the interworking for various radio access

technologies as shown in Figure 1-2.

Uplink bearer binding verification

SGSN

The EPC architecture supports both the Gn/Gp SGSN and the S4 SGSN.

The Gn/Gp SGSN inherits the SGSN functions of the 2G/3G network and supports the access

of the existing GERAN/UTRAN to the GGSN. The S4 SGSN is the upgraded version of

Gn/Gp SGSN, supporting the access of GERAN/UTRAN to the EPC as well as the

switchover between the GERAN/UTRAN and E-UTRAN.

The SGSN is introduced to provide packet data services. The main function of the SGSN is to

forward IP packets imported/exported by the UEs in the SGSN service area. The functions of

the SGSN include the following:

Routing and forwarding data packets from all mobile users in its own SGSN area

Encryption and authentication

Session management

Mobility management

Logical link management

Charging data records (CDR) generation and export for collection of information about

radio resource usage

GGSN

The GGSN is a functional entity that provides packet data services. It routes and encapsulates

data packets between the GPRS/UMTS network and an external PDN. The GGSN provides

the following functions:

Interface to an external PDN

The GGSN serves as a gateway for an MS to access the external PDN. For the external

network, the GGSN serves as a router for all devices in the GPRS/UMTS network.

GPRS/UMTS session management

The GGSN sets up a connection between an MS and the external PDN.

Data routing and forwarding

The GGSN receives data from the MS and forwards the data to the external PDN. It also

receives data from the external PDN and selects a transmission channel in the

GPRS/UMTS network based on the destination address to forward the data to the SGSN.

Charging for postpaid services

The GGSN generates and outputs CDRs based on the usage of the external network by

the subscribers.

Call control and service switching functions for prepaid services

For prepaid services, the GGSN serves as a service switching point (SSP) that connects a

mobile network and an intelligent network.

HSS

The Home Subscriber Server (HSS) stores all subscriber data related to services provided by

EPC networks.





12

CG

As a device in the EPC system, the CG collects and pre-processes CDRs generated by the

GGSN, S-GW, P-GW,or EPSN. The CG also provides an interface to the billing center. When

an EPC user accesses the Internet, several NEs generate CDRs. Each NE may generate

several CDRs. The CG pre-processes the CDRs, and then sends them to the billing center.

This helps reduce the work load of the billing center. If the CG is applied in the network, the

GGSN, S-GW, P-GW ,or EPSN does not need to provide an interface to the billing center.

PCRF

A PCRF is a policy and charging control element.

In a non-roaming scenario, there is only a single PCRF in the Home Public Land Mobile

Network (HPLMN) associated with one UE's IP-CAN session. The PCRF terminates the Rx

interface and the Gx interface.

In a roaming scenario with local breakout of traffic, there may be two PCRFs associated with

one UE's IP-CAN session:

Home PCRF (H-PCRF) that resides within the HPLMN

Visited PCRF (V-PCRF) that resides within the Visited Public Land Mobile Network

(V-PLMN)

The functions of the H-PCRF include the following:

Terminate the Rx interface for home network services

Terminate the S9 interface for roaming with local breakout

Associate the sessions established over multiple interfaces (S9 and Rx), for the same

UE's IP-CAN session

Terminate the Gx interface for home network services in the roaming scenario

The functions of the V-PCRF include the following:

Terminate the Gx and S9 interfaces for roaming with local breakout

Terminate the Rx interface for roaming with local breakout and visited carrier's

application function (AF)

PCEF

The UGW9811 can be deployed as an EPSN or function as a GGSN/P-GW that provides the

PCEF function.

When a PCRF is deployed, the UGW9811 reports user plane events to the PCRF, detects

service flows and implements gate actions, QoS control, and charging control policies as

required by the PCRF.

When no PCRF is deployed, the UGW9811 implements the configured gate actions, QoS

control, and charging control policies for specific subscribers, APNs, or services.

AAA Server

The Authentication, Authorization, Accounting (AAA) server complies with the Remote

Authentication Dial in User Service (RADIUS) protocol. The AAA server can also be

deployed in other systems in addition to EPC networks.





13

DNS

There are two types of Domain Name Servers (DNSs) on the EPC network:

DNS located between the P-GW and the PDN

It is used to resolve the domain name of the PDN; equivalent to a common DNS on the

Internet.

DNS located on the EPC core network

When the UE requests access to an external network for packet services, the MME

requests the DNS to resolve the domain name according to the access point name (APN).

After the IP address of the corresponding P-GW and S-GW are obtained, a transmission

channel can be established between the UE and P-GW.

The DNS can also be deployed in other systems in addition to EPC networks.

BM-SC

The BM-SC implements the following functions:

Distributes and controls eMBMS services.

Performs access control and charging on subscribers who use broadcast services.

Authenticates subscribers on the public land mobile network (PLMN), initiates eMBMS

bearer requests, and schedules and delivers eMBMS services.

OCS

The online charging system (OCS) provides the service-specific credit control function (CCF).

On the UGW9811, the OCS can identify prepaid users and rate, assign quotas, and deduct

fees for prepaid users.

2.4 Carrier-class Platform Enables More Flexible Services

The UGW9811 presents an ideal and flexible solution for wireless data communication to

network carriers. In order to achieve this, it utilizes Huawei's Universal Switching Router

(USR) hardware platform which boasts high reliability and high-level data throughput and a

software platform that seamlessly integrates wireless telecommunication technologies and

data communication technologies.

The USR is a carrier-class network switching device that is compliant with industry standards.

Developed on the basis of Huawei Versatile Routing Platform (VRP), the software of the

UGW9811 inherits the integrated routing technology, IP Quality of Service (QoS), Virtual

Private Network (VPN), and security technology of the VRP and perfects the functions

specific to applications in wireless telecommunication.

2.5 High Reliability Design Ensures the Normal Operation of Products

Reliability is crucial for both carriers and end users and the UGW9811 was designed with this

need in mind. The design team focused on ensuring reliability in terms of hardware, software,

networking and O&M to ensure optimal operations.

Hardware reliability

The UGW9811 supports hot plugging and hot backup of key boards, possesses a

double-channel power supply system, and is protected from over-voltage and

over-current.

The DMPU subcards can work in load-sharing mode. Therefore, when one DMPU

subcard is faulty, the other DMPU subcard takes over all services, and the system

triggers a fault alarm. If the DMPU subcards are required but unavailable or if the

DMPU subcards are overloaded, the system triggers an alarm.

Software reliability

The UGW9811 is capable of overload control, traffic control, resource check, system

software backup, configuration files check and automatic fault detection. This ensures

reliable running. The unique charging data record (CDR) cache function guarantees a

reliable billing system. The hot patch technology helps to ensure the normal software

running.

Networking reliability

The route backup and route load-sharing functions can prevent single point failures on

networks, helping to build highly reliable networks. The Eth-trunk function can prevent

the failure of a single port from affecting services.

Operation and Maintenance Reliability

SSL: The UGW9811 ensure data confidentiality for operation and maintenance.

When the UGW9811 upgrade failed, it can rollback previous version automatically. In

this way, the remote update failed service restore time can be reduce.

The UGW9811 provides the patch rollback function to ensure the reliability of running

patch.

2.6 Security Design Protects Customer Profits

One of the primary concerns of both carriers and end users is network security. Bearing this in

mind, security requirements were taken into consideration in every aspect in the design of the

UGW9811. The result is that multiple measures were adopted to ensure the protection of

information which translates to satisfied customers and therefore profits to carriers.

To ensure security in the UGW9811 system the following measures are taken:

Strict verification of operator identity
